Kinetis M Series MCUs

Ultra-low-power, smart-metering MCUs with precision analog, security
and HMI peripherals

Kinetis M Series MCUs
Based on the ARM® Cortex®-M0+ Cores

NXP's Kinetis M series MCUs are based upon the low-power ARM® Cortex®-M0+ core and are designed for single-chip 1, 2 and 3 -phase electricity meters as well as flow meter and other precision measurement applications.

Kinetis M series MCUs include a powerful analog front end consisting of multiple 24-bit Sigma Delta ADCs, Programmable Gain Amplifiers, voltage reference with low drift over temperature and a phase shift compensator. A large range of security features including a memory protection unit, external tamper detection pins, iRTC with tamper detect and a random number generator provide protection of supplier/user data within the MCU and from the MCU to the power grid. A low power segment LCD controller supports up to 288 segments and 8 backplanes.
